The Watts–Strogatz model is a mathematical model used to generate small-world networks, which are characterized by high clustering and short average path lengths. Introduced by Duncan J. Watts and Steven H. Strogatz in their 1998 paper, "Collective dynamics of ‘small-world’ networks," this model captures the balance between local interconnectedness (like regular lattices) and global interconnectedness (like random networks).
Social statistics indicators are quantitative measures that provide insight into various aspects of society, helping researchers, policymakers, and organizations assess social conditions, changes, and trends. These indicators can cover a wide range of dimensions related to human behavior, well-being, and social structures. Here are some key areas often evaluated through social statistics indicators: 1. **Demographics**: Indicators such as population size, age distribution, gender ratios, and migration patterns that help understand the composition and dynamics of a population.
Borexino is an underground neutrino observatory located at the Gran Sasso National Laboratory in Italy. It is designed primarily to detect low-energy neutrinos, which are nearly massless and electrically neutral particles. The primary goal of the Borexino experiment is to study solar neutrinos produced by nuclear reactions taking place in the sun, thereby providing insights into solar processes, fundamental physics, and the properties of neutrinos.
The Enriched Xenon Observatory (EXO) is a scientific experiment designed to search for neutrinoless double beta decay, a rare nuclear process that, if observed, would provide important insights into the nature of neutrinos and help address fundamental questions in particle physics and cosmology. The primary goal of EXO is to study the properties of neutrinos, particularly their mass and whether they are their own antiparticles. EXO utilizes a large volume of liquid xenon as the detection medium.
The HERMES (Heavily-Enhanced Relative Muon and Electron Scattering) experiment was a particle physics experiment conducted at the HERA (Hadron-Electron Ring Accelerator) facility at DESY (Deutsches Elektronen-Synchrotron) in Hamburg, Germany.
The TOTEM (TOTal Elastic and diffractive cross section Measurement) experiment is a component of the Large Hadron Collider (LHC) at CERN, focused on studying diffraction and elastic scattering processes in high-energy proton-proton collisions. It aims to measure the total cross section, elastic scattering cross-section, and diffractive processes. TOTEM employs specialized detectors positioned around the collision point to capture particles that are scattered at very small angles, which are indicative of elastic scattering events.
The Super Proton Synchrotron (SPS) is a particle accelerator located at CERN, which serves as an injector for the Large Hadron Collider (LHC) and has also been used for various experiments in high-energy physics. Over the years, numerous experiments have utilized the SPS for a range of research in particle physics, including studies of hadron interactions, neutrino physics, and the investigation of new particles.
The NA60 experiment is a particle physics experiment conducted at the CERN (European Organization for Nuclear Research) facility, specifically at the Super Proton Synchrotron (SPS) accelerator.
The NPDGamma experiment is a physics experiment designed to study the properties of the neutron, particularly its magnetic moments and interactions. Specifically, it focuses on measuring the $γ$-ray emission from the capture of neutrons by protons. This involves investigating the transition between neutron spins and magnetic moments, which has implications for understanding fundamental symmetries in physics, such as charge-parity (CP) violation. The experiment is conducted at the Oak Ridge National Laboratory using a polarized neutron beam.
The Yale Wright Laboratory is a facility associated with Yale University, primarily focusing on research in the fields of astrophysics, particle physics, and related disciplines. It is named after the former Yale physicist, Professor of Physics, and Nobel laureate, Robert J. Wright. The lab includes various experimental and observational projects that explore fundamental questions about the universe, including the behavior of matter and energy at the smallest scales.
"Look Around You" is a British television series that originally aired from 2002 to 2005. Created by Robert Popper and Peter Serafinowicz, the show is a parody of 1970s and 1980s educational programs. Each episode is formatted like a science documentary, exploring various scientific topics in a humorous and absurd manner. The show is known for its deadpan delivery, low-budget aesthetic, and surreal comedy.
CERN does not specifically have an accelerator known as "Hadron Linacs." However, it does operate several types of particle accelerators and facilities involved in hadron physics. Here's a brief overview of the concepts involved: 1. **Hadron Accelerators**: These are particle accelerators specifically designed for hadrons, which are subatomic particles made up of quarks. Protons and neutrons are examples of hadrons.
The Compact Linear Collider (CLIC) is a proposed particle accelerator designed to collide electrons and positrons at high energies. The CLIC concept is being developed by CERN (the European Organization for Nuclear Research) as a next-generation linear collider to complement the capabilities of the Large Hadron Collider (LHC). ### Key Features of CLIC: 1. **Linear Design**: Unlike circular colliders, which can accelerate particles in a loop, CLIC is a linear accelerator.
The High Luminosity Large Hadron Collider (HL-LHC) is an upgrade project for the Large Hadron Collider (LHC), the world's largest and most powerful particle accelerator, located at CERN (the European Organization for Nuclear Research) near Geneva, Switzerland. The HL-LHC is designed to significantly enhance the LHC's luminosity, which is a measure of the collision rate of particles within the accelerator.
The International Linear Collider (ILC) is a proposed particle accelerator aimed at studying the fundamental particles and forces that make up the universe. It is designed to collide electrons and positrons (the antiparticles of electrons) at high energies, enabling scientists to investigate various aspects of particle physics in a controlled environment.
Intersecting Storage Rings (ISR) is a type of particle accelerator design that allows for high-energy collisions between beams of particles. The concept is specifically associated with the way two storage rings are configured to cross each other, enabling the simultaneous circulation of two particle beams that can collide at specific interaction points. In an ISR setup, particles—typically protons or other hadrons—are accelerated and stored in separate rings. These rings are designed to intersect at certain locations, where the particles collide head-on.
The Low Energy Antiproton Ring (LEAR) was a facility at CERN (the European Organization for Nuclear Research) designed to facilitate experiments involving antiprotons. Operational from 1996 to 2000, LEAR provided a unique capability to produce and manipulate low-energy antiproton beams, allowing for a variety of experimental investigations in particle physics.
An "organizing center" can refer to several different concepts depending on the context, including biology, project management, or social science. Here are a few interpretations: 1. **Biology**: In cellular biology, an organizing center often refers to a structure that plays a crucial role in the organization of cellular components.
A Neutrino Factory is a scientific facility designed to produce large quantities of neutrinos, which are subatomic particles with very little mass and no electric charge. These facilities use particle accelerators to create neutrinos through various processes, typically involving the decay of pions or muons.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
